COVER' FB GASQLINE TANKS.

'To awkom it may concern:

vBe itkn'own that I, TokUsABUno ToKU- man, a subject of the Emperor of Japan, residingin the city and county of Los An.- -goles and State of California have invented a new and useful Cover for (irasoline Tanks, of which the following is a specification.

This invention has relation to an imroved cover for gasoline tanks, and the e, and its objects are to'provide a cover which may be. qui, y applied and removed for the the tank, and which, when removed. will not become lost, and which, when applied,'will not par loose; the

invention being especially app icable to aumobile.' tanks and radiators.

' .v Other objects and advantages may appear in .the lsubjoined detail description.

In the drawings, Figure 1 is a side velevation of my improved tank cover,-F1`g. 2 is a Asectional view of the same. Fig. 3 is a bperspective detail 'view of the valve disk and plunger. Fi 4 is a erspective d etail to the tank opening. Fig. 5 is a sectional and plan view through. the to 'part of the cap'. Fig. 6 is a cross-section o the cap, with the levers removed therefrom. Fig. 7 is a fragmentary and sectional detail view of a modified form. Fig. 8 is a perspective detail view of a modified form having but one handle. Fig. 9 is a bottom plan view of the lyand .into the top chamber 17, of cap 18.

A" chain 19, is attached to the bottom of the disk 14, and provided on its extremity with a retaining member 20, which,A when the cover is removed, remains inside of the tank and prevents the cap from becoming lost.

The nipple 11 has two opposily disposed and projecting pins 21, adapted to engage with grooves 22, in cap 18. A spring 23, .interposed between the valie disk 14: and partition wall 24, serves to normally press view of the nipp e`adap d to be attached applicatie mea February 2e, 192s. semi No. 621,302.

the cap upwardly and thereby maintain the pins 21 in the end `portion 25, of slotsA 22. To press the cap downwardly relative to the' nipple, I .provide levers 26, pivotanlly mountedon bearings 27, and having their inner extremities 2 8, in engagement with a bar 29, fixed to valve stem 116. On' depressing levers 26, thecap is forced downwardly so that the pins 21l will enter the arcuate portion 30, of grooves 22. The cap, by

means of levers 26 and handles 31, may be' then rotated' throu ha small arc, whereupon the pins 21 wi l passthrough the par-t 32, of grooves 22, allowing the cap to be removed from the nipple. The chain 19 and anchor 20, then prevent the cap from be coming lost. To prevent a vacuum in the tank, provide a minute opening 33, in the valve disk.

In the modified form shown in Fig. 7,'I employ .a single lever 34 for operating the ;valve and valve-stem. Other operative parts are similar to the referred form.

In the modified orm shown in Figs. 8 and 9. I'employ a4 single valve operating lever 34, and aA single handle 35 on the cap. Other operative parts are similar to the preferred form.

From the foregoing description and the drawings, it may be seen that I have provided a simple and efficient cover for automobile radiators and gasoline tanks, andthe like, the device-being instantly detachable for the purpose of refilling the tank or radiator, automatically locked against detachment when applied, and which will not become lost when detached. It is'obvious that minor changes in the form and details of construction and arrangement of parts may ,he made in accordance with the appended .claims without departing from the spirit of the invention orsacrificing anyof its advantages.

'VVhatis claimed is: I

1. In a quick-detachable tank` cover," the combination with a nipple adapted-t be secured to the tank opening, of projecting pins on opposite sides of the nipple, an annular ange projecting inwardly within the nipple and forming a valve seat, a ca'p for the nipple having integral arms, and grooves on the inner wall thereof adapted, for engagement with the projecting pins on the nipple, a valve member within thenipple and an integral stem on the valve member, levers pivotally mounted'relative to the cap, a cross bar on the end of the valve stem, slotted extremities on the levers and having integral and opposed projecting nipple having grooves in engagement with" pins, and an annular inwardly proJeeting valve seat flange, Gf a valve disk for engagement .with the valve aeat, a cap for the the nipple pins, a partition wall in theap, a spring interposed between the partition wall and valve disk, a valve stemprojecting through the partition wall, a cross bar` on the extremity of the stem, levers.pivot ally mounted inthe cap and projecting therefrom, slotted inner extremities on'fthev 'levers in engagement with. the cross' bar, a
